Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ''Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and service ...

Vertical Farming
Vertical farming is the practice of growing crops in vertically stacked layers. It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. Some common choices of structures to house vertical farming systems include buildings, shipping containers, tunnels, and abandoned mine shafts. , there is the equivalent of about of operational vertical farmland in the world. The modern concept of vertical farming was proposed in 1999 by Dickson Despommier, professor of Public and Environmental Health at Columbia University. Despommier and his students came up with a design of a skyscraper farm that could feed 50,000 people. Although the design has not yet been built, it successfully popularized the idea of vertical farming. The main advantage of utilizing vertical farming technologies is the increased crop yield that comes with a smaller unit area of land requirement. Another ...

Agriculture In Canada
Canada is one of the largest agricultural producers and exporters in the world. As with other developed nations, the proportion of the population agriculture employed and agricultural GDP as a percentage of the national GDP fell dramatically over the 20th century, but it remains an important element of the Canadian economy. A wide range of agriculture is practised in Canada, from sprawling wheat fields of the prairies to summer produce of the Okanagan valley. In the federal government, overview of Canadian agriculture is the responsibility of the Department of Agriculture and Agri-Food. Major agricultural products Various factors affect the socio-economic characteristics of Canadian agriculture. The 2006 ''Census of Agriculture'' listed seven: Quantity and type of farms; Biogeography: crop and land use areas; land management practices; Quantity of livestock and poultry; Agricultural engineering: Farm machinery and equipment; Farm capital; Farm operating expenses and receipt ...

Building-integrated Agriculture
Building-integrated agriculture (BIA) is the practice of locating high-performance hydroponic greenhouse farming systems on and in mixed-use buildings to exploit synergies between the built environment and agriculture. Typical characteristics of BIA installations include recirculating hydroponics, waste heat captured from a building's heating-ventilation-air condition system (HVAC), solar photovoltaics or other forms of renewable energy, rainwater catchment systems, and evaporative cooling. The earliest example of BIA may have been the Hanging Gardens of Babylon around 600 BC. Modern examples include Eli Zabar's Vinegar Factory Greenhouse, Gotham Greens, Dongtan, Masdar City, and Lufa Farms. The term building-integrated agriculture was coined by Ted Caplow in a paper delivered at the 2007 Passive and Low Energy Cooling Conference in Crete, Greece. Background Applications of BIA are motivated by trends in patterns of energy use, global population, and global climate change. ...

Controlled-environment Agriculture
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming -- is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop. Production takes place within an enclosed growing structure such as a greenhouse or plant factory. Plants are often grown in a soilless medium in order to supply the proper amounts of water and nutrients to the root zone as well as supplemental lighting to ensure a sufficient daily light integral. CEA optimizes the use of resources such as water, energy, space, capital and labor. CEA technologies include hydroponics, aeroponics, aquaculture, and aquaponics. Different techniques are available for growing food in controlled environment agriculture. Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertic ...

Nutrient Film Technique
Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels. History NFT was pioneered in 1965 by Allen Cooper at the Glasshouse Crops Research institute in Littlehampton, England. In an ideal system, the depth of the recirculating stream is very shallow, little more than a film of water, hence the name 'nutrient film'. This ensures that the thick root mat which develops in the bottom of the channel receives adequate air exposure. Description A properly designed NFT system is based on using the right channel slope, the right flow rate, and the right channel length. The plant roots are exposed to adequate supplies of water, oxygen and nutrients. In earlier production systems, there was a conflict between the supply of these requirements, since excessive or deficient amounts of one result ...

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroponics
Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in aqueous solvents. Terrestrial or aquatic plants may grow with their roots exposed to the nutritious liquid or in addition, the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution by secondary metabolites. Transgenic plants grown hydroponically allow the release of pharmaceutical proteins as part of the root exudate into the hydroponic medium. The nutrients used in hydroponic systems can come from many different organic or inorganic sources, including fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions. Plants are com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Heat Island
An urban heat island (UHI) is an urban or metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The temperature difference is usually larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the UHI effect is from the modification of land surfaces. A study has shown that heat islands can be affected by proximity to different types of land cover, so that proximity to barren land causes urban land to become hotter and proximity to vegetation makes it cooler. Waste heat generated by energy usage is a secondary contributor. As a population center grows, it tends to expand its area and increase its average temperature. The term heat island is also used; the term can be used to refer to any area that is relatively hotter than the surrounding, but generally refers to human-disturbed areas. Monthly rainfall is greater downwind of cities, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
